Data mining has broad applications that reach beyond scholarly and scientific research and provide internet search engine services that are commonly used forms of Text and Data Mining('TDM') of websites. The exceptions and limitations for data mining provide a competitive advantage in the global race for policy innovation because it permits researchers to conduct computational analysis - TDM on any materials to which they have access. For this purpose, Japan and the EU added limitations on copyright to legalize some TDM research through amendments to copyright law, and the U.S. copyright law has allowed data mining by the fair use provision. On the other hand, there are no explicit exceptions and limitations for data mining under the Korean Copyright Act, and there are no cases considering data mining fair use. We review comparatively exceptions and limitations on copyright which will help to encourage AI-related business by using more data smoothly through the mining process and extracting more valuable information.

This paper analyzes the existing copyright management and copyright sharing model and discusses the limitations. It then proposes a consortium Blockchain-based copyright management model in which the service platform participates as a node, and discusses how to combine the My Data concept with Blockchain and smart contracts. Also, Blockchain-based CP-ABE is introduced and applied to the proposed model as a way for users to define access policies and store copyright data in encrypted form on the storage of the online service providers (OSP). Compared with the existing copyright management model, the proposed model allows the copyright holder to focus on copyright registration, license content design, and sharing, as the data subject. And it is expected to be able to transparently manage the usage records and the basis for the settlement of the copyrighted data that are shared and used on each platform.

Nigeria Copyright Commission is saddled with the responsibility of ensuring adherence to the copyright law in Nigeria. However, it has been observed in the last decade that copyright right issue is still rampant in Nigeria. Therefore, this study analyzed cases that the Commission in involved in between years 2008 to 2018. The study adopted citation analysis. The study collected data from three selected law reports, which include Intellectual Property Law Reports, Nigerian Weekly Law Reports and Nigeria Law Intellectual Property Watch. It was found that Nigerian Law Intellectual Property Watch has the highest number of reports of cases involving Nigerian Copyright Commission while none was reported by Nigerian Weekly Law Reports. It was also found that most of the cases handled by the Commission were on copyright infringement. The study concludes that Nigerian Copyright Commission has been paying credible attention to issue that surrounds software infringement but there has been little attention paid to book piracy. Moreover, it was established that the poor attention given to book piracy may entrench the publication of pirated copy and would subsequently lead to poor library service provision at the long run.

This paper proposes a method to protect the copyright of creators' content shared through an online sharing platform in a legal battle. When creators upload their independent creation content to the online sharing platform, it automatically upload information necessary for copyright effect to this system. The data warehouse of this system is as a private blockchain for to ensure non-repudiation and transparency of the information. We present that the data warehouse is to build as Hyperledger Fabric in this paper. And We present the transaction data structure of the blockchain to prevent orphan works. We also dealt with how to build a website where users can conveniently check the data (copyright related information) of this blockchain.

There have been proposed various copyright protection protocols in network-based digital multimedia distribution framework. However, most of conventional copyright protection protocols are focused on the stability of copyright information embedding/extracting and the access control to data suitable for user's authority but overlooked the privacy of copyright owner and user in authentication process of copyright and access information. In this paper, we propose a solution that builds a privacy-preserving proof of copyright ownership of digital contents in conjunction with keyword search scheme. The appeal of our proposal is three-fold: (1) content providers maintain stable copyright ownership in the distribution of digital contents; (2) the proof process of digital contents ownership is very secure in the view of preserving privacy; (3) the proposed protocol is the copyright protection protocol added by indexing process but is balanced privacy and efficiency concerns for its practical use.

In 2D-to-3D video conversion process, the virtual left and right view can be generated from 2D video and its corresponding depth map by depth image based rendering (DIBR). The depth map plays an important role in conversion system, so the copyright protection for depth map is necessary. However, the provided virtual views may be distributed illegally and the depth map does not directly expose to viewers. In previous works, the copyright information embedded into the depth map cannot be extracted from virtual views after the DIBR process. In this paper, a new copyright protection scheme for the depth map is proposed, in which the copyright information can be detected from the virtual views even without the depth map. The experimental results have shown that the proposed method has a good robustness against JPEG attacks, filtering and noise.

The paper analyzes a copyright owning firm's incentive to enforce its copyright in the presence of file-sharing networks. I devise a two-period model where a copyright owner sells two different versions of a creator's information good, and show that the firm's overall profits are enhanced by a strategy of differential inter-temporal enforcement of the copyright protection, compared to strategies of no enforcement or full enforcement in both periods. If the firm enforces no copyright protection in the first period, the low-valuation consumers may make and consume copies that are imperfect substitutes for the original information good. If there is a significant increase in the willingness-to-pay of some low-valuation consumers after they experience the information good, the firm can extract the increased consumer surplus by enforcing a positive level of copyright protection in the second period. Social welfare, however, is maximized in the case of no enforcement.

The paper looks at protecting copyright owners in Nigeria: a panacea for intellectual development. A descriptive survey design was adopted in carrying out the study. The sample size for the study was 112. Three research objectives guided the study. The study utilized a self-developed questionnaire for data collection. A total of 112 copies of the questionnaire were distributed to librarian and lecturers, out of which 108 copies were duly filled and returned, representing 96.4%. The collected data was arranged in frequency and analyzed using percentage and mean score. The findings revealed that protection of copyright will encourage creators of intellectual works, and that if authors are well remunerated there is likelihood of adequate availability of various publications to meet information needs of Nigerians. The result showed that the right to intellectual properties is one of the ways to encourage intellectual development. The finding revealed that copyright protection provides security for intellectual product and does not negatively affect the availability of intellectual materials. Based on the research findings, it was recommended that owners of intellectual property deserve good earnings for their intellectual works in order to promote Knowledge proliferation and availability so as to meet the reading needs of the citizens at the various levels. The study also recommended that all cases relating to copyright violation in our courts should be summarily dealt with. The study advocated that the provision on the punishment should be reviewed such that it could deter people from infringing on authors rights.
